    OpenAI drops GPT-5.5-Cyber preview to supercharge critical infrastructure defense

    OpenAI just launched GPT-5.5-Cyber in limited preview for critical infrastructure defenders, alongside its Trusted Access for Cyber program. Vetted security researchers get fewer classifier refusals to run authorized penetration tests and red teaming without guardrails getting in the way. It is built to level the playing field against attackers, though users must adopt phishing-resistant authentication by June 1, 2026.

    OpenAI gives security defenders a freer GPT-5.4

    OpenAI just expanded its Trusted Access for Cyber program and introduced GPT-5.4-Cyber, a fine-tuned model built specifically for defensive cybersecurity work. The permissive variant lowers refusal boundaries on legitimate security tasks and adds binary reverse engineering to analyze compiled binaries for vulnerabilities. It allows verified defenders to leverage frontier capabilities without running into standard safety guardrails.
